ID:228003 Physical synthesis settings are on. The Quartus Prime software may create and/or rename nodes in the design. Intel recommends that you generate a VQM and use it as the design source file.

CAUSE: You specified one or more options for optimizing netlists during fitting, and attempted to back-annotate the current design. However, the Quartus Prime software cannot perform these netlist optimizations on a back-annotated design.

ACTION: Click Yes to back-annotate the design, or click No to cancel the operation. If you want to use one of these netlist optimizations on a design and then back-annotate the design, Intel recommends that you generate a Verilog Quartus Mapping File (.vqm) that indicates the duplicated LUTs that the Quartus Prime software generated and/or resynthesized while fitting the design.
